These labels can be found on every Solar Photovoltaic (PV) System, and are used as warnings to protect the public. In the solar industry, safety is paramount. Any mistake when operating or maintaining solar power can result in serious injury, so it’s important to understand the dangers and proper safety requirements. Solar energy, a power source that originates from the sun, is not inherently dangerous. However, once it has gone through the “Photovoltaic Effect”, sunlight is converted into electrical energy.
